Full of neat surprises and twists, this powerhouse slasher from 1986 is certainly one of the better late '80s efforts.

A group of young people assemble at their friend Muffy's house on a remote island for a weekend retreat. Soon, Muffy begins behaving strangely, fierce secrets begin to emerge, and bodies begin to pile up...but is any of it real?

This genial horror has some light moments without being obnoxious, and there's a great turn by Amy Steel as Kit. The rest of the cast is also a pleasure and there's a nicely effective score by Charles Bernstein.
